FRANCIS J. STROBEL, OF CHICAGO, ILLINOIS, ASSIGNOB TO F. J. STROBEL & CO., A

CORPORATION OF DELA'WARE.

LEAF-BINDER.

Application filed August 28, 1915.

17 0 all whom it may concern:

Be it known that I, FRANCIS J. S'rnoBnL, a citizen of the United States of America, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Lea-fBind ers, of which the following is a specification.

The main objects of this invention are to provide an improved form of leaf-binder of the kind wherein a plurality of adhesive tabs are arranged for use in separately securing loose or single leaves in covers, folders, etc.; to provide an improved arrangement of the tabs whereby a number thereof may be secured in the form of a strip to a cover or folder, or so that a few may be quickly and conveniently detached from the others for use in binding a small number of sheets together; to provide an improved integral connection of said tabs to each other whereby they coact one with another in being held in a normal folded position, but so arranged that they may be separately selected for use without interfering with the retention of the remaining tabs in said folded position; to provide improved protecting means for cov ering said tabs so as to retain them in their folded positions; and to provide a leaf binder of this kind which is inexpensive in construction and convenient to use.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which Figure l is a perspective view of a fragment of the improved leaf-binder, the parts being arranged in unfolded positions.

Fig. 2 is a similar view with the binding tabs folded over onto the binding strip.

Fig. 3 is a fragmentary view of the binder with the protecting flap folded over onto the tabs, being the form in which it is marketed.

Fig. 4 is a perspective view of the folder showing the manner in which the binder is used for supporting letters or other papers in a folder.

Fig. 5 is an enlarged fragmentary sectional detail illustrating the manner in which these binders are adapted to be built up in a folder of this kind.

In the construction shown in the drawings, the leaf-binder comprises a binding strip 1, tabs 2 and a protecting flap 3. The binder is made from a strip of paper or other suitable material, which preferably has previously had an adhesive applied to one Specification of Letters Patent.

face thereof and which, in the form of a strip, is passed through a suitable machine equipped with punches and folding mechanism for punching out the recesses or slots 4 and forming the rows of perforations 5 and 6 (as shown in Fig. l) and then folding the tabs 2 over onto the binding strip 1 and the flap 3 over onto the tabs 2, as shown in Fig. 3.

Ihe formation of the recesses or slots 4, as shown in Figs. 1 and 2, provides enlarged ends or heads 7 on the tabs 2 which are integrally connected one to another by narrow portions 8. The portions 8, although extremely small, are sufficient to hold the tabs together so that they retain all unseparated ones in their folded positions, as shown in Fig. 2, and at the same time allow one tab to be readily separated from the others.

' The perforations 5 extending across the binding strip 1 in alinement with the apertures 4, and the line of perforation 6 forming the hinge connection of the flap 3, permit one or more of the tabs 2 to be readily separated from the remainder of the tabs by simply tearing them off along the desired line of perforations. This is particularly advantageous where a few tabs at a time are needed, as they can be separated from the others without the use of a pair of scissors or a knife, such as would be the case if the perforations were omitted.

The leaf-binder herein shown is usually marketed in strips of ten or twelve inches long, folded as illustrated in Fig. 3. When it is desired to use these binding strips in folders for correspondence or other papers, a binder 9 of the desired length, is moistened along the binding strip 1 and pasted into the folder 10, as illustrated in Fig. 4. Then, as the correspondence or other papers are to be filed away, the flap 3 is folded back so as to permit access to the tabs, whereupon tabs 2 at each end are separated from the others, moistened, and pasted to the letters 11 as indicated. The flap 3 is then folded back over the remaining folded tabs 2 so that they are retained and protected in their folded positions. After all of the available tabs 2 have been made use of, and it is desired to continue the use of the folder for filing further papers, the flap 3 is torn from the binding strip 1 along the line of perforations 6 and the gummed side thereof moistened and pasted over the binding strip, as

indicated by 3 in Fig. 5. This tends to build up a second binder, as indicated in Fig. 5 so as to insure a better grip of the tabs 2 on subsequent papers.

l/Vhere the tabs are to be used for other purposes, such as mounting camera prints in albums, or binding inserts in sheet music to the cover, only a few tabs at a time are required. The desired number in a group are then torn from the binder along the lines of perforations. The part 1 is pasted to the cover or folder, as the case may be, and thetabs 2 separately attached to the prints or leaves or whatever is to be fastened therein.

Although but one specific embodiment 'of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

I claim 1. An article of manufacture comprising a binding strip, a plurality of adhesive tabs hinged thereto along one edge and normally folded over onto said strip, and a flap hinged along the other edge of said strip and folded over onto said tabs.

2. An article of manufacture comprising a binding strip, a plurality of adhesive tabs attached along the edge thereof, and perforations extending transversely across said strip in alinement with the space between said tabs.

3. An article of manufacture comprising a binding strip, a plurality of adhesive tabs attached along one edge thereof, there being perforations extending transversely of said strip in alinement with the spaces between said tabs, and a flap having a perforated connection to the other edge of-sai'd strip.

4:. An article of manufacture comprising a binding strip, a plurality of adhesive tabs integrally hinged thereto, said tabs being integrally attached one to another at points distant from their connection to said strip, and parallel perforations extending transversely across said strip in alinement with the space between said tabs.

5. An article of manufacture, comprising a binding strip, a plurality of adhesive tabs attached along the edge thereof and nor mally folded over onto said strip, and a flap having a perforated hinge connection to the other edge of said strip and foldable over onto said tabs.

6. An article of manufacture comprising a binding strip, a plurality of adhesive tabs attached along the edge thereof and normally folded over onto said strip, and an adhesive coated flap having a perforated hinge connection to the other edge of said strip and foldable over onto said tabs.

7 An article of manufacture comprising a binding strip, a plurality of adhesive tabs attached along the edge thereof and normally folded over onto said strip, perforations extending transversely across said strip in alinement with the space between said tabs, and a flap having a perforated hinge connection to said strip along the other edge thereof and adapted to be folded over onto said tabs.

Signed at Chicago this 24th day of August, 1915.
